xtremeleo, you are also here. I have a SGTI for track. My problem is the blooming Siemens VDO. I cant tune it without using a Piggy back or Changing all the wiring plus ECU to MMC.
I am also waiting to do a rebuild as engine in SGTI is 160,000 KMS. Only suspension and chassis improvements were put in. Plus off course final drive from Mivec, CUSCO LSD and roll cage.
But my main problem is I cant tune the Siemens.

i had this problem as well as i was trying to do a BOT for a 4g15 svdo. on contrary to the majority, svdo outperforms mmc in terms of fuel and engine efficiency. Power sports tuning equipment can be used alongside with svdo whilst maintaining the ecu's operation and simultaneously accommodating other mods on the car.
